[horde] imp and mailer

[Uttiya Chowdhury]

Hi all, 
imp has a backends.php, but how mail is sent from imp is determined by the mailer setting in horde's setup. I found it counter-intuitive. I thought:
* imp should use it's own configuration (as set in backends.php) to send mail
* if horde needs to send mail, it will use the values set in the mailer tab

If the mailer tab settings determine how imp will send mail, why do we have that section in imp anyway?

Thanks.
